zero vt.

1. To set to 0. Usually said of small pieces of
data, such as bits or words (esp. in the construction `zero
out'). 2. To erase; to discard all data from. Said of disks and
directories, where `zeroing' need not involve actually writing
zeroes throughout the area being zeroed. One may speak of
something being `logically zeroed' rather than being
`physically zeroed'. See scribble.
